Introduction

Information about the health of the landscapes we manage is essential to achieve the BLM mission (Federal Land Policy and Management Act of 1976). It enables BLM to measure the benefits that these lands and waters provide, understand the effects of multiple uses, and thus create management plans to sustain these landscapes for future generations.

This report provides information about the health of terrestrial and aquatic ecosystems. This information was collected on-the-ground by field biologists who measure and assess important indicators related to ecosystem health. In terrestrial ecosystems, they focus on cover and composition of plant species, plant height, gaps between plant canopies, and stability of soils. In aquatic ecosystems, they focus on water quality, stream morphology, and biological characteristics. These quantitative measurements and qualitative assessments were collected under the BLM Assessment, Inventory, and Monitoring (AIM) program. For more information about AIM, see http://aim.landscapetoolbox.org/learn-3/about/.

This report also includes relevant standard geospatial datasets. Some relate to ecosystem health, while others provide contextual information about landscapes such as the management activities occurring there.

This report was generated through partnership among the BLM National Operations Center, USDA-ARS Jornada, and the BLM National Aquatic Monitoring Center.

Report Purpose and use

The purpose of this report is to describe key indicators of ecosystem health across an area of interest. This information can be used to evaluate whether or not goals or desired conditions are being achieved across BLM lands, an essential step in adaptive management. Specific management applications include but are not limited to: treatment effectiveness, Land Health Standards evaluation, sage-grouse habitat assessments and Resource Management Plan effectiveness. Tables, graphs, and other content from this report can be pasted into decision-making documents, or the entire report can be used as an appendix to such documents.

The standard core indicators contained in this report are relevant to management questions across all BLM ecosystem types, as identified through the BLM AIM Strategy and related efforts (TN440, TR1735-1). This report also contains standard national geospatial datasets managed by the BLM National Operations Center and partners. These geospatial datasets provide spatial and management context for the standard AIM core indicators.

Report Organization

This report has five main sections. The introduction sets the stage. The data summary provides contextual information that is helpful for interpreting the results, including the list of indicators, time period, timing of sampling, and maps.

Report results begin with the objectives, benchmarks, and landscape thresholds section. This contains a table of desired conditions on the landscape and whether they were achieved based on available data. This table can be used by BLM land managers to evaluate whether goals or management objectives were achieved. This table is a summary of results for all indicators.

The condition estimates by objective section identifies the condition of each indicator for each area of interest or reporting unit. Condition refers to the proportion of land or water resources that is achieving desired values known as benchmarks. This section provides further detail about each row of the table in the previous section and can be used as supporting information for the conclusions drawn from that table.

Finally, the appendices contain additional background information on AIM, the core indicators and methods, and the analysis approaches used to generate this reports.

Information Sources

This report summarizes and analyzes information collected from an AIM project. The following information sources were used in the analysis presented in this report:

  • The Monitoring Design Worksheet summarises the goals and objectives of the monitoring project.
  • The AIM Data Analysis Template provides data summaries of the AIM data collected for the project and clearly states the objectives, indicators, benchmarks, and required landscape proportions for each objective.
  • AIM data from TerrADat are the quantitative data collected in the field for the project.
  • The project’s Sample Design Database captures all of the technical details of the project sample design (e.g., sample frame, stratification, initial point selections, fate of the sample points, and design weights). This information is used to adjust the sample point weights to produce unbiased estimates.
  • Spatial data files defining the different levels of reporting units for which estimtes will be generated from the AIM data.
  • Spatial or tabular Information defining benchmark classes (i.e., categories assigned to each sample point for the purpose of evaluating an indicator against a benchmark that may change across a landscape).
  • (OPTIONAL) - Additional sample points from the BLM Landscape Monitoring Framework to supplement the AIM project data.
  • (OPTIONAL) - Remote sensing products such as the Grass/Shrub continuous variable predictions or the Landfire EVT map to supplement the quantitative field-derived estimates.

Interpreting the Results

Results in this report can be used to evaluate whether goals regarding ecosystem health are being achieved across a landscape. Success criteria for each goal are specified as measureable monitoring objectives that include a natural resource indicator of interest, a benchmark that identifies desired values of that indicator, and the proportion of the landscape that should meet the benchmark. This report provides statistical estimates of the proportion of the landscape achieving the monitoring objectives, in the form of tables, graphs and other information (see summary in objectives, benchmarks, and landscape thresholds or detailed info in condition estimates by objective). BLM land managers requesting the report supplied relevant goals, monitoring objectives and reporting units as part of the process of designing their monitoring effort (see http://aim.landscapetoolbox.org/design). Upon receipt, it will be the responsibility of BLM land managers to evaluate whether goals are achieved and make management recommendations.

Consider important contextual information when you evaluate whether goals are achieved:

  • Monitoring objectives: Are benchmarks well-justified and based on best available knowledge? Are desired proportions informed by management goals and landscape context?
  • Reporting unit: Is this appropriate to evaluate whether goals are achieved?
  • Timing of sampling: Is sample timing appropriate for the ecosystem type as well as the goals and objectives for the reporting unit? Does sample timing vary between years? Does sample timing affect your results?
  • Sample spread/point fates: Are monitoring sites distributed across the area of interest? Were some areas systematically missed, which could lead to bias?

Analysis Outputs

In addition to this report from which charts and tablar data can be copied/pasted, the following standard outputs are created as part of this analysis:

  • Data table containing the plot-level raw data from TerrADat combined with the adjusted point weights (input for analysis).
  • Data table listing each monitoring objective with its indicator(s), benchmarks, and required landsdcape proportions (input for analysis).
  • Data table listing the categories assigned by indicator to each point based on the benchmarks (input for analysis).
  • Data table containing the analysis results of the category analyses by reporting unit (spsurvey cat.analysis output table).

Plot Sampling Summary

Not all points originally selected as part of a design can be sampled. Selected points may not be accessible or when evaluated may be deemed to not even be part of the population. The Rejection Criteria page on the AIM Landscape Toolbox website describes the rejection criteria for evaluating plots. To properly adjust the sampling weights and ensure unbiased estimates, it is important to know the fate of each of the originally-selected points. The graph below summarizes the point fates for the sample design(s) considered in this report.
